The Bose L1® Model II with B1 Bass Module is a portable line array PA system that's great for applications such as houses of worship, schools and universities, live music performances, mobile DJs, and more. This modular system can set up and tear down in minutes thanks to its interlocking components, which also makes transport to and from your gig a breeze.

The L1 Model II with B1 Bass Module system consists of two array speakers with a total of (24) 2.25" HF drivers, a foldable power stand with I/O panel, and a B1 bass module with dual 5.25" LF woofers. The power stand's I/O consists of a 1/4" input that can accept balanced or unbalanced signals, a 1/4" line output for an external amplifier or powered subwoofer, a Speakon output for connecting one bass module, and an Ethercon port to connect to Bose's T1 ToneMatch® audio engine (sold separately). The optional T1 ToneMatch provides 4 additional channels of input with three XLR-1/4" combo inputs and a stereo pair of 1/4" inputs. Each channel includes independent volume controls along with a master volume control to easily balance each channel to your needs. The T1 ToneMatch is also equipped with EQ and multiple effects such as reverb and delay to add an extra layer of depth to your performances.

This system is designed to reach crowds of up to 500 people, and with a total power rating of 500 Watts and a maximum 115 dB SPL output means you'll have plenty of volume for your performance. L1 Model II also offers a 195° horizontal by 0° vertical dispersion pattern that will reach everyone in the crowd evenly to ensure that no one misses a word you say or a note you play.

Bose L1 Model II with B1 Bass Module Features:

  • High-performing, powered, portable two-way loudspeaker system with a 195° H x 0° V nominal dispersion designed for the production and reproduction of live music, music playback, speeches, and A/V sound reproduction
  • 24-driver articulated line array loudspeaker technology produces wide, uniform sound coverage throughout the entire listening area - even off to the extreme sides
  • Convenient front-to-back coverage, 24 drivers mounted in a vertical line array produces less drop off in sound pressure level per doubling in distance than a conventional point source
  • Retractable folding leg mechanism for easy transport
  • Lightweight, interlocking components
  • Digital Ethercon port provides single-wire connectivity for the T1 ToneMatch audio engine (sold separately)

Bose L1 Model II and L1 Compact - Review (Video Transcription)

"Hi, we're here at the Bose booth with Tony Christina and we're gonna talk about the L1 Portable Sound System. It's a fantastic portable sound system, extremely lightweight but great frequency response, all the way from uh, 50 Hz all the way on up, because it has a subwoofer system. What makes this really unique, Tony, from what I understand is that a musician can actually sit in front of this and play and not have feedback." [Tony speaking] "That's very true Ron. The, uh, the L1 System was originally designed for a musician to potentially take the place of both your PA and the monitoring system, thus simplifying setup, uh, providing more consistent sound for not only the musicians performing on stage, but for the audience as well. Uh, but for the house of worship community, we're also finding that the L1 can be really powerful as just a, a loudspeaker system, uh just for front of house. And the wide and even coverage, the great frequency range that you mentioned... as well as the ability of the product to throw a, a very long distance without dropping off in SPL levels in the back make it an ideal solution." [Ron speaking] "Uh, so this is really a mini line array actually." [Tony] "It is. It is. And it operates as a true line source, and, uh, but it is portable. It is self-powered. It's self-contained. So whether you're using it as a primary system, for something like a fellowship hall, or even as a personal sound system for just a musician or small group of musicians, potentially it's a great solution." [Ron] "So, since it's a line array, I know I can sit in fron of it with a microphone and an instrument and I'm not gonna get feedback. Is that right?" [Tony] "Well, you can make anything feedback if you try hard enough..." [Ron] "Yeah..." [Tony] "But yeah, this product's very very resistant to feedback. And again, because it was designed orginally for musicians, uh, you can crank this thing way up, stand right in front of it with an open mic, and be fine." [Ron] "Okay. So it looks really big... I mean it's taller than I am. So why do we think this is portable?" [Tony] "Well, it's much taller than me. But the nice thing is it breaks up into 4 pieces. The array breaks in half. The power stand folds up and the wings fold in. And then the bass module's obviously separate. So you can basically haul this in in two trips, balanced in your arms, and there's nothing here that weighs over about 35 pounds." [Ron] "K, so my wife could haul this into a venue then?" [Tony] "Absolutely. Or, potentially the L1 Compact, which - 29 pounds, you can haul the whole thing in one arm, set it up in about one minute, and get great sound for a, a smaller room with one loudspeaker." [Ron] "Okay, so, Tony, I don't know that I'm a believer in this... Right? You know...I, I've used a couple of these and they sound great, but if I'm not a believer in this, then how to I get to try this out and make sure it works for me?" [Tony] "Well we're supporting CCI Solutions' "Try It Free" program. And we know that hearing's believing right? And every room's different. Every application's different. So we want to give, uh, people the opportunity to hear it in their own church, uh, the way they use it, with the way they worship, and, uh we, we've got those systems available, both the Model II and the Compact." [Ron] "Okay, so somebody just has to give us a call at CCI Solutions. Go ahead and set it up. And we'll send a system out for 'em to try for a week or two and they can see if it works for them." [Tony] "Absolutely. And we'd encourage people to do it. Again, hearing's believing." [Ron] "Absolutely. Hearing is believing. So from the Bose booth with the L1 Compact and the L1 Portable Line Array System, Ron Simonson."

Bose L1 Model II Portable Loudspeaker System - Impressions (Video Transcription)

"The biggest thing again is just the clarity in going from the 450s that we're using ...S1 450s to those, it just opened it up. It's like taking a wet towel off of the speaker. So all of a just opens up just all this air in there and it just breathes. It's like taking the lid off of a good pot of something cooking and all of a sudden what's contained in there just comes out, and now you can really smell everything. Well now when we turn those on it's like now we can really hear everything. It was really, really cool and we really like it a lot."
